2011 Map of Frog Coulee

About this map

The Missouri River defines the northern edge of this landscape in Roosevelt County, where the high plains are carved by a complex network of coulees and drainage systems. This 2011 survey illustrates a region shaped by agricultural management and early 21st-century rural infrastructure, notably the irrigation and water management structures such as Harfo Dam, Foss Dam, and R Schmitz Number 1 Dam. The terrain is marked by distinctive formations like Balls Bluff and deep-cut valleys including Promised Land Coulee and Big Basin Coulee. Cultural history is anchored by sites like the Saint Bernards Church Cemetery and Lynd Cemetery, which serve as quiet markers of the community's ancestral footprint. A network of rural routes, including County Rd 321 and Road 146, provides access across the drainage of Charlie Creek and Charley Creek, mapping out the modern persistence of this prairie geography.
